commit 3c0bb3107703d2c58f7a0a7a2060bb57bc120326 upstream.
The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Fix the SET_ROM_WAIT_STATES request which erroneously used
usb_rcvctrlpipe().

commit 70b52f09080565030a530a784f1c9948a7f48ca3 upstream. According to the eMMC Spec: "When command queuing is enabled (CMDQ Mode En bit in CMDQ_MODE_EN field is set to ‘1’) class 11 commands are the only method through which data transfer tasks can be issued. Existing data transfer commands, namely CMD18/CMD17 and CMD25/CMD24, are not supported when command queuing is enabled." which means if CMDQ is enabled, the FFU commands will not be supported. To fix this issue, just simply disable CMDQ on the ioctl path, and re-enable CMDQ once ioctl request is completed.

[ Upstream commit a7ab186f60785850b5af1be183867000485ad491 ] The card timing and the bus frequency are not changed atomically with respect to calls to the set_clock() callback in the driver. The result is the driver sees a transient state where there's a mismatch between the two and thus the inputs to the phase correction calculation formula are garbage. Switch from dev_warn() to dev_dbg() to avoid noise in the normal case, though the change does make bad configurations less likely to be noticed.

It has been reported that usage of memcpy() to/from an iomem mapping is invalid,
and a recent arm64 memcpy update [1] triggers a memory abort when dram-access-quirk
is used on the G12A/G12B platforms.
This adds a local sg_copy_to_buffer which makes usage of io versions of memcpy
when dram-access-quirk is enabled.

R-Car M3-W ES3.0 is marketed as R-Car M3-W+ (R8A77961), and has its own
compatible value "renesas,r8a77961".
Hence using soc_device_match() with soc_id = "r8a7796" and revision =
"ES3.*" does not actually match running on an R-Car M3-W+ SoC.
Fix this by matching with soc_id = "r8a77961" instead.

Inserting an SD-card on an Intel NUC10i3FNK4 (which contains a GL9755)
results in the message:
mmc0: 1.8V regulator output did not become stable
Following this message, some cards work (sometimes), but most cards fail
with EILSEQ. This behaviour is observed on Debian 10 running kernel
4.19.188, but also with 5.8.18 and 5.11.15.
The driver currently waits 5ms after switching on the 1.8V regulator for
it to become stable. Increasing this to 10ms gets rid of the warning
about stability, but most cards still fail. Increasing it to 20ms gets
some cards working (a 32GB Samsung micro SD works, a 128GB ADATA
doesn't). At 50ms, the ADATA works most of the time, and at 100ms both
cards work reliably.
